Due to gravity, the

hooks

1212 and 1222 of the first and

second arms

121 and 122 are close to each other, and the pair of arms of the multiple group arm assembly 12 jointly hold the workpiece tightly. When the hook 1212 on the first boom 121 and the hook 1222 on the second boom 122 are moved away from each other by an external force, the workpiece is allowed to be detached from the spreader 1.

Referring to fig. 5, the supporting member 123 includes a connecting plate 1231, a supporting plate 1232, a turning plate 1233, and a handle 1234.

One end of the connecting plate 1231 is rotatably connected to the second boom 122. Specifically, a rotating hole is opened at one end of the connecting plate 1231, the rotating shaft 1224 of the second boom 122 penetrates through the rotating hole to realize the rotatable connection between the connecting plate 1231 and the second boom 122, and the connecting plate 1231 is located between the two boom bodies 1221.

Two support plates 1232 are connected to the end of the connection plate 1231 opposite to the second boom 122. The two support plates 1232 are arranged in parallel at intervals, and the connecting plate 1231 is sandwiched therebetween.

A locking groove 1236 is formed at the bottom of the supporting plate 1232, and a space is formed between the locking groove 1236 and the connecting plate 1231 along the length direction of the supporting plate 1232.

The size of the locking groove 1236 is matched with the limiting shaft 1214 on the first suspension arm 121, so that the locking groove 1236 can be locked with the limiting shaft 1214, and the support 123 is supported between the first suspension arm 121 and the second suspension arm 122 to keep the two suspension arms in the open state.

Specifically, the locking groove 1236 is hook-shaped. In this embodiment, the cross section of the clamping groove 1236 is similar to a fishhook shape, so that after the clamping groove 1236 is clamped with the limiting shaft 1214, the lower circumferential surface of the inner side of the limiting shaft 1214 is abutted against the inner circumferential wall of the clamping groove 1236, and the limiting shaft 1214 is limited from being separated from the clamping groove 1236.

A handle 1234 is also provided on the end of support plate 1232 remote from attachment plate 1231. Specifically, the handle 1234 includes two side portions spaced apart in parallel and a grip portion connected between the two side portions. Both side portions are perpendicular to the support plate 1232, and the grip portion is parallel to the support plate 1232. The operator manipulates the support member 123 by grasping the handle 1234, such as by lifting the catch 1236 upward to disengage the catch 1236 from the restraint shaft 1214 and pressing downward to catch the restraint shaft 1214 in the catch 1236.

A rotation shaft is fixed to the support plate 1232 and connected between the two support plates 1232. Specifically, in the present embodiment. The rotation shaft is fixed above the clamp groove 1236.

The turning plate 1233 is sandwiched between the two support plates 1232 and is rotatably connected to the rotary shaft. When the roll-over plate 1233 overturns to one end of the handle 1234, the handle 1234 abuts against the roll-over plate 1233 and stops the roll-over plate 1233 to continue to rotate downwards, and at the moment, the roll-over plate 1233 shields the clamping groove 1236. When the turning plate 1233 is turned to the connecting plate 1231, the connecting plate 1231 abuts against the turning plate 1233 to stop the turning plate 1233 from continuing to rotate downwards, and at this time, the clamping groove 1236 is exposed.

In this embodiment, when the turning plate 1233 blocks the fastening groove 1236, the top of the turning plate 1233 goes upward beyond the supporting plate 1232.

Because the turning plate 1233 is clamped between the two supporting plates 1232, the turning of the turning plate 1233 is limited, and the turning plate can rotate only by external force.

The utility model discloses a hoist 1's application method as follows:
